Re: Fwd: bash script bugs

Have a script:

Twos things do not work as they should. By order:
1) Output in command line for nest commands
  ls /cygdrive/d/install/buf/*.html
  dir /cygdrive/d/install/buf/*.html
is same:
/cygdrive/d/install/buf/a.html
/cygdrive/d/install/buf/b.html

while output for ./FileGroupContentsChange.sh
/cygdrive/d/install/buf/*.html is only
/cygdrive/d/install/buf/a.html

This is no bug. It's a user error. If you want FileGroupContentsChange.sh to show
both files you either need to escape the '*' in the parameter your pass to it or have
the script process all the parameters (i.e. $*) with the internal 'ls' command.


2) (not critical but not "classical") Both command line script and
outputs for current folder in one line:
ls returns
FileGroupContentsChange.sh  cygcheck.out  sources
and so ./FileGroupContentsChange.sh do

That seems "classical" to me. If you prefer 1 file per line, use the '-1' flag.
